| Abstract |
We have evaluated the wavelength-proportional arrangement of virtual microphones (WPVM) applied to the triangular microphone array in a real car environment. Beamforming is effective for speech enhancement in in-car communication. However, it is difficult to install a sufficient number of microphones for beamforming in a car. In this paper, we propose to achieve high speech enhancement performance with a small number of microphones in a car by using virtual microphone technique, which increase the number of microphones virtually. We applied virtual microphone technique to triangular microphone array in a car and evaluated adaptive beamforming performance. As a result, the WPVM is shown to be effective to improve the performance of speech enhancement in a car. |
